RADIO FREQUENCY IDENTIFICATION COMMUNICATION SYSTEM AND METHOD THEREOF
First Claim
1. A radio frequency identification (RFID) communication system that uses a standard channel for RFID communications, comprising:
- a reader, when actuated, initializing a designated channel and transmits at last one designated message at a first time interval through the designated channel; and
at least one active RFID tag comprising;
a channel initializing module, when actuated, initializing the designated channel to communicate with the reader though the designated channel;
a receiving module, triggering a receiving state at a second time interval to receive the designated message;
an identification (ID) module, which, after receiving the designated message, compares an ID code recorded in the designated message with a pre-determined ID code and determines the validity of the designated message according to the comparison result; and
a processing module, when the designated message is valid, performing processes corresponding to an executing routine command included in the designated message.

Abstract
A radio frequency identification (RFID) communication system and method is provided to resolve the power-consuming problems of an active RFID tag while operating at a receiving mode in a long duration. A designated channel is established between the reader and the RFID tag, and also the reader sends a designated message so that the actuated active RFID tag can receive the designated messages and dynamically enter into a receiving mode. Therefore, normal communications may be conducted between the reader and the RFID and the usage period or technical performance can be improved as well.

11. An RFID communication method that uses a standard channel for RFID communications, comprising the steps of:
-
initializing a designated channel on a reader and at least one active RFID tag for the reader and the RFID tag to communicate via the designated channel; continuously transmitting at least one designated message in a first time interval via the designated channel by the reader; triggering a receiving state at a second time interval by the active RFID tag for receiving the designated message; after receiving the designated message, comparing a pre-determined ID code with an ID code recorded in the designated message, thereby checking the validity of the designated message; and when the designated message is valid, performing processes corresponding to an executing routine command in the designated message. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
